NOTES:

1.Within a given interrupt level, the lower vector address has high priority. For example, DCH has higher priority than DEH within the level IRQ5 the priorities within each level are set at the factory.

2.External interrupts are triggered by a rising or falling edge, depending on the corresponding control register setting.
